Описание The new solid-phase reagent is synthesized by previous modifying the surface of silica gel with l-(4-sulfophenyl)-3-methyl-5-(benzoxazol-2-yl)formazan for Ni(II) ions determination in water. The high effective colour change (Δλ = 200 nm) is observed due to complex-formation reaction reagent with nickel (II) ions. Increasing toxicant concentration is accompanied by growth the colour intensity of the solid-phase sorbent, which form the basis of colour scale development for the Ni(II) ions determination in the range 10-100 mkg/ml. Ni(II) ions determination can't be disturbed by the presence of Co(II) ions, alkali or alkali-earth metal ions. Proposed technique is high rapid (its max duration is 2-3 min), ordinary (it is required neither expensive equipment nor qualified staff to use the technique) and ecological friendly. © Published under licence by IOP Publishing Ltd.
